PROFET™+ 24V | Automotive Smart High-Side Switch

About PROFET™ + 24V for CAV power distribution

PROFET™+ 24V is specially designed for CAV applications, such as BCM for trucks and buses, braking (ABS and ESP), transmission valves, steering or safety systems, decentral ECUs, ADAS loads, fuse and relay replacement, pneumatic or hydraulic valves for excavators, fork lifters, and agriculture vehicles. The family offers an R_DS(on) range from 10 to 200 mΩ. The modular family concept consists of single, dual, and four channel devices. Because of the modularity, different devices can be used on the same PCB footprint, which saves costs in case the load requirements change. Finally, the products are also pin and function-compatible with Infineon's 12 V high-side power switch family (PROFET™+ 12V).

About PROFET™ + 24V family for CAV power distribution

All products are designed to withstand 24 V load dump conditions (58 V for 400 ms). A steeply switching slew rate reduces power losses and saves energy. Comprehensive protection functions (also for long cables), fast current sense diagnostic with very tight kILIS accuracy, and an extended operating voltage range ensure the highest operational reliability. Two products with lower current limitations ("ERB" variants) allow to switch loads via long cables (e.g., for trailers). All kinds of loads (valves, pumps, motors, sensors, bulbs, LED, etc.) up to 10 A nominal load current can be switched. Within the family also, Infineon's first PRO-SIL™ ISO 26262-compliant high-side power switch is offered. Most of the products have the TDSO-14 package.

ISO 26262 - Dependable electronics based on Functional Safety (FuSa)

With Infineon’s PROFET™+ 24V, designers are well prepared for todays and upcoming challenges of the automotive electronic or electrical (E/E) architectures which demand components that meet the requirements for PRO-SIL™ ISO 26262-compliant and PRO-SIL™ ISO 26262-ready classifications used in fail-safe systems and available also for fail-operational power distribution systems. The BTF6070-2ERV is Infineon’s first PRO-SIL™ ISO 26262-compliant high-side power switch.

PROFET™+ 24V Design Support

Infineon offers a range of design-in materials, which include application notes, evaluation boards, PCB design data, simulation models, and also online simulations. Those materials can be found on each product page in the "Design Support" chapter. In addition, we offer a dedicated tool suite for Smart Power Switches and Gate Driver ICs for automotive power distribution.

Infineon Smart Power Switches and Gate Driver Tool Suite supports system architects and hardware designers from the idea to the realization. This suite allows the user to select the right smart power switch or gate driver IC for a specific load using one of the “Finder and Selection” tools. Together with the different “Simulation and Modeling” tools, various application scenarios can be simulated for a product. The results can be documented in the report tool and verified with “Configuration” tools plus the corresponding evaluation boards.

PROFET™+24V is a scalable family (RdsON 10 – 200 mΩ) of smart 24V high side switches with advanced protection and diagnostic features.

PROFET™+ 24V switches are designed to be used for 24 V Automotive application (CAV) and industrial applications. All kind of loads (valves, pumps, motors, sensors, bulbs, LED, more) up to 10A nominal load current can be switched.

The PROFET^TM+ 24V is especially designed for CAV applications, such as BCM for trucks and busses, braking (ABS, ESP) and transmission valves, steering / safety systems, decentral ECU’s, ADAS loads, fuse and relay replacement as well as  pneumatic/ hydraulic valves for excavators, fork lifters and agriculture machines. Because of extended operating voltage range (up to 48V), plenty of industrial applications are addressable too.

As user of PROFET™+24V devices, you will get in favor of the following benefits:

• Cost savings: No external components needed because current sense diagnostic is integrated with high kILIS accuracy
• Cost savings: Cheaper device can be used on same design spot in case of load requirement change or reuse of the design for 12V application
• Efficiency increase: Steeply switching slew rate reduces power losses and saves energy
• Extended use case: Long cables can be switched thanks to lower current limitation devices
• Extended use case: High position accuracy for linear valves and energy savings for safety application, thanks to BTF6070-2ERV (ISO26262 qualified, ASIL B)
• Cost savings: All devices are 24V load dump resistant (no external components for protection circuit needed)
